  • Development of Accelerated Life Test Method of

    This paper proposes a new accelerated life test method of hydraulic pump used in vehicles, which have multiple alternating loads. For determination of life time of hydraulic pump for given field conditions with respect to duty cycle, the equivalent load and speed of this unit has to be determined.

  • An accelerated life test model of hydraulic piston

    Hydraulic piston pumps are important mechanical power conponents, and accelerated life tests (ALT) of them are widely conducted. After an ALT, ALT model is needed to give the lifetime of hydraulic piston pumps under baseline condition with ALT data. This paper proposes a physics-statistics-based ALT model for hydraulic piston pumps.

  • Accelerated Life Test Model for Life Prediction of

    The safety factor of hydraulic piston pumps and motors shows a tendency to decrease due to high pressurization, high speed and low weight/volume realization to enhance the output density. Therefore, more effective test models are necessary to predict the exact life. The sensitive parameters in the endurance life test are speed, pressure and ...

    The chart shows that pump life will be reduced to 1,440 hours if operated simultaneously at maximum pressure and maximum speed. But if run at reduced conditions of 2,000 PSI and 1,000 RPM, it would have the fantastic life rating of 67,500 hours. Similar charts can be prepared for any pump.
